There are many stepper support blocks in kittenblock. You may precisely move your robot, turn in precisely degree or even draw an arc.

The Pulse Per Meter block is to calibrate the linear moving. The theoretical value is calculated by checking how many pulses we need send to steppers to drive 1 meter. You may fine-tune this value if you find the robot not moving precisely.

The Wheel Base block indicate the distance of wheels, this is also a theoretical value, not the distance you actually measure the wheelbase distance. This is used when calculating the turning degree and arc moving, you may find a clue in the kittenbot firmware source code.

Hit the block group and check if the robot move 20cm forward and back. Make sure you are still using USB cable connection, for now, we will show how to use wifi module to do the online mode functions later.
